CIRCUIT ARRANGEMENT AND METHOD FOR OPERATING SEMICONDUCTOR LIGHT SOURCES

摘要

Various embodiment may relate to a circuit arrangement for operating a load, including an input for inputting a mains input AC voltage, a power converter circuit, a converter circuit which converts the mains input AC voltage rectified by the power converter circuit into an output voltage, a control circuit for controlling the converter circuit, and a linear regulating circuit which sets a predetermined load current at the load. The load current is a direct current with a uniform current intensity. The control circuit controls the converter circuit in such a manner that the current intensity of the load current is reduced when the output voltage is at a minimum.
